cormmnn scaaan mm: AND wmrnaa My invention relates to a com ined screen frame and weather stripping for casement winfor screens made or nylon or other ductile synthetic material.

Screening made of 'nylon or equivalent synthetic resinous and other ductile materialsare liable to be cut or sheared when forcefully clamped or squeezed between hard surfaces such as. a window sash and metal frame or when mounted to a metal screen frame by forcing a metal spline to wedge the screeninto the frame,

as is common in the mounting of metal wire screens.

Moreover, theoretically, the conventional rigid metal frame screens are supposed to fit tightly dows suited particularly, though not limitatively part of this specification and wherein:

and frame sections to insure an eflicient weather I seal therebetween. I The-above and further objects and novel aspects-of my invention will become more apparent from the following detailed description taken in reference to theaccompanving drawings forming Figure 1 is a perspective view showing the novel screen frame secured to a standard casement window frame as seen from the inside of the buildagainst the window sash. However, in practice.

such an ideal condition is not always obtainable. The screen frame may be slightly warped or the window member may not have a true plane. Accordingly, therefore, the screen frame remains ajar along portions of the crack perimeter suf- 'ficient to allow insects to come through and resulting in other disadvantages and defects well knownx Accordingly, an object of the present invention is to provide a novel screen frame construction which is simple in design and easy to install and which will insure a complete and eflicient' seal bridging the. entire perimeter between the of spring metal weather stripping for casement windows have been developed in the past, all of which have proven expensive to install and unsatisfactory in various respects. These weather 8 a Figure 2 is an enlarged sectional view showmg one form of a combined screen frame and weather stripping according to the invention and taken .on line 2-2 of Figure 'l, omitting fastenings and operating means.

Another object is to provide a combined re silient screen holder and weather stripping for casement windows adaptedto insure a close and perfect fit along the entire screen perimeter and Figure 4 shows a cross-section of the weathering element and resilient screen holder embodied in Figures 1 to 3,

Like reference numerals identify like parts throughout the difierent views of the drawings.

As more particularly shown in Figures 1 to 3, the numeral l0 represents the frame section of a metallic casement window of any suitable construction known in the art, such as in the form of a Z-bar as shown in the example illustrated. Numeral II shows the sash or ventilator section of the'window suitably hinged in a manner well assemknown and formed either in a single section or a plurality of members and having secured thereto proved screen frame and weather stripping ac-- cording to the invention is adapted for attach ment to the inside of the window framelll in anyv suitable'mannerand is constructed as described 1 in the following.

A rigid frame l8 of suflicient stillness has side and cross-bars which may or may not be secured at their junctions in any appropriate manner as by welding, rivets or'the like. fllhe individual frame, members are preferably hollow as shown and are made of shaped suitable sheet material such as steel, aluminum alloy or any other suitable material and may be either integral or with their edges in abutting contact or secured together in any suitable manner. This frame is secured to the window frame ill with a strip or member I 4 of resilient material such as rubber, or the ,like interposed therebetween in the manner shown in th drawings. This resilient 'member serves as a gasket to provide a tight seal or close contactthroughout the entire perimeter of the screen I! interposed and clamped between the'member I4 and the frame l3. Due to the flexibility of the member ll the perimeter of the screen will be secured tightly and without cracks to the window frame "I, while at the same time making it possible to use a screen of relatively soft or ductile material such as nylon or any other equivalent resinous synthetic or other ducthe principles of the invention. In thi modification, the resilient screen spline and weathering member 20 is shaped to dovetail with the metal frame I3 secured to the frame section III. For this purpose the cross-section of the resilient member 20 has a lower curved or vaulted surface followed by opposite lateral projections 22 and "tile material without the danger of cutting or M shearing the screen during the clamping operexclude insects inthe open. position of thewindow.

In order to obtain a two-point weather seal by the member ll pressing against or engagingboth theframe and sashsections HI and II,-

respectively, member 1! is arranged to project sumciently'into the window area in such aman neras to contact'the sash section I l in the closed position as shown in the drawings and to insure a perfect and efllcient two-point weather seal,

\ whereby to completely eliminate dust, air or water frommenetrating to the inside of the window. In the example shown in the drawings, the screen frame I3 is mounted. by means of brackets ll secured to the frame III by screws or bolts or in any other suitable manner. Any other con nection or mounting maybe employed to suit special, and existing requirements as .is under- @swod.

As pointed out above-the combined resilient screen holder and weathering strip It may consist of rubber, rubberized or any equivalent ma- 4 terialpossessing anadequate resiliency. In the example shown in Figures 1 to '4, it is made from a flat strip having its lengthwise edges reversely bent and secured to the strip by gluing or the like as shown 'in Figure 4 to provide apair of adjacent loop shaped sections capable ofbeing compressed so as to provide an eflicient seal in the manner shown in'Figure 2 in the assembled or operative position. Ir desirable, the loop engagking the sash llmay be reinforced along its inner edge aslshown at I! to provide addedstiifness and improve the weathering action. The window .is shown provided from the inside'in a manner well understood and hnown in the art.

Referring to Figures 5 to 1, 1 have shown a modified construction of acombined screen'frame' terminating in extensions or weathering elements engaging the frame I0 and vent section II of the window as shown in Figure 5. The rigid screen frame I3 is of channel-shaped cross-section and has an open inner side with its free ed es reversely bent inwardly as shown at 23 and adapted to dovetail with the projections 22 of the resilient member 20 in the inserted position, whereby to firmly hold the spline 20 and interposed screen l5 within the frame l8.

During assembly, the end of the screen is placed over the metal frame l3 and the resilient spline of frame In as shown in Figure 5, while the inner extension 2| of member 20 engages the inner Z-bar of the vent'section H upon closing of the window. In this manner, there is obtained. an efllcient two-point weather seal engaging both the sash and frame sections of the window. At the same time, the member 20 provides an eiilcient seal along the perimeter of the screen l5 in the manner pointed out hereinabove.

The screen spline and weathering member 20 may be provided with a ;central metal core or wire 24 for stiffening purposes if desirable. The mitered corners of member 20 may or may not be joined as they will tend to'squeez together under pressure in the assembled or clamp d po ition of the spline. The curved bottom shape of the spline 20 tend to greatly improve and ease the insertion into the metal'frame It. A simple tampering tool can be employed so as to simultaneously ram the spline in both sides of the metal frame. The screen ,is stretched taut when the resilient spline is forced into the metal frame.

' it should become necessary to renew the screen.

. with a suitable operating mechanism l'l or any known onstruction for opening and closing the ventilator H This screen mounting results in a tight seal of the screen perimeter, enabling both the use of relatively'soft or ductile screen-material such as nylon and at the same time excluding any possibility of cracks between the screen and mounting frame.

There is thus provided by the invention a com-' frame sections to exclude 'wind'. wateror dust in the closed position of the window.

Referring to Figure 8 there is shown a further embodiment of,the invention wherein the resilient weathering member 28 is provided with extensions engaging both the frame In and vent sections II in a manner similar to Figure 5, but is secured to the outside of the frame I! by gluing or cemen- .titlously or in any other appropriate manner.

construction and weather stripping embodying Frame II is provided with an inner reentrant porcient weathering seal between theventila r and Iclaim:

'tion adapted to receive a further resilient spline -26 of metal, rubber or the like for securing the screen IS in the manner] shown and readily understood from the drawings. This construction has the advantage that the screen may be removed or replaced without removing the weather stripping such as during the winter months. Further provisions may be made to replace the screen by a storm sash of known'con'struction within the scope of this invention. 4

'As is evident, the combined weather stripping and resilient screen holder disclosed and described herein may be modified in various manners within the broader scope and spirit of the invention.

- Thus, the rigid frame It ma be a solid bar or strip of metal or non-metallic material and the resilient member it may assume various other shapes and constructions to conform with different window structures and other requirements. Ina special embodiment, the member it may be formed as a unit with. the screen I 5 to constitute a peripheral frame or binding for the latter and made of interwoven strands of synthetic resinous material, a screen holder comprising a rigid member secured to said. frame section and a rubber member sealing the perimeter of said screen, said rubber member having a portion arranged to engage said sash section when the sash is closed to operate with said sash section inthe closed position to act as weather stripping for said window.
